[PATCH v13 02/12] ACPI: Add comments to clarify some #ifdef statements

[Mario Limonciello]

With nested #ifdef statements it's sometimes difficult to tell
which code goes with which statement.
* One comment said it was for the end of a CONFIG_X86 block,
  which was wrong as it was actually a CONFIG_IA64 block.
* Another block for CONFIG_ACPI didn't have a comment.

Fix the comment for the CONFIG_IA64 block and add a comment
for the CONFIG_ACPI block.
